  This 
  species 
  somewhat 
  closely 
  resembles 
  Euthrips 
  cingu- 
  

   Jatus, 
  Karny, 
  from 
  which 
  it 
  is 
  easily 
  separated 
  by 
  the 
  pro- 
  

   thoracic 
  bristle 
  at 
  each 
  hind-aiifyle, 
  tlie 
  uniform 
  liglit 
  yellow 
  

   colour 
  of 
  body, 
  and 
  the 
  coloration 
  of 
  the 
  antennae. 
  The 
  

   coloration 
  of 
  tiie 
  wings 
  is 
  about 
  the 
  same. 
  Tlie 
  relative 
  

   lengths 
  of 
  the 
  antennal 
  joints 
  are 
  also 
  distinctive.
